any help will be appreciated

If it is working in console, it sounds like the endpoint is likely incorrect. Is that value the same as given by songpal discover? You could adjust your homeassistant's logger to include debug logging for songpal and get more output what is happening.

If it is not working with the cli tool, then this is likely a duplicate of #29 . What device is it?

Thanks, Yes I realized that it’s my music server that doesn’t support the method “getSupportedApiInfo”

I did some test and can only use some of the API functions, my device is HAP-S1, not listed as supported device, but it does have the API and I can control it using cellphone APP

Can you post the output of songpal discover? It will show what services the device offers, which can give a clue of what is/can be supported (soundbars generally support guide, audio, avContent and system). I'm currently doing some code refactoring, one goal being to be able to use those devices without getSupportedApiInfo in the end.

For the time being you can look up commands you need (the source gives some hints) and use songpal command <service> <method> <parameters> to call them manually.

./songpal discover

This is what I get using songpal discover

I did some tests with the methods in the API document, only some are supported, others either return "no such method" or just empty json file. I can get information of the currently played song, use paly/pause feature, control volume, get next and previous song, set power off

Basic control features are supported, I guess all Sony device with this API should support it, so maybe you can make a hard-coded version of songpal with just some basic control features, that's what most people need. or you can let the users to choose what API method to use

And thanks for your help

Alright, I'll close this as a duplicate for #29 - thanks for your input!
